Question

(7 – 4x) = 9
plz steps ​

Answer 1

x= -1/2

Explanation:

Mkay... You would start off by getting rid of the parentheses because they aren't needed here...

7 - 4x = 9

Now, you would add 4x to both sides to get rid of the subtraction...

7 = 9 + 4x

Then, you subtract 7 from each side....

0 = 2 + 4x

Moving on, you would subtract 2 from each side...

-2 = 4x

And then divide 4 on each side to get...

x = -1/2

And there's your answer!

Answer 2

x = -2/4

Explanation:

You always want to leave the variable alone-

-4x + 7 = 9

To do that you need to get rid of the seven and that can be done by subtracting/adding it by its opposite value in both sides of the equation.

-4x = 2

Get rid of that 4 by dividing from both sides of the equation-

x = -2/4
